Rives: What your are describing sounds like trying to measure the impulse response of the room.
1. What would you use as a noise burst source?
2. What would be your detector? I assume you would locate the detector at the listening position. [I can do an FFT in MATLAB, but need to get the time series data input to my computer to do the plots you describe]
3. What characteristic behavior would you be looking for in the waterfall plot? A more rapid decay of energy in this band?
4. What calculations would you make? Anything besides the peaks and nulls of standing waves? I have an irregular shaped room , but do have a program I use for SONAR development that would give me the normal mode structure for a room like this.
Thanks for the input. I would like to give this a go, as long as I have access to the tools I need to make the measurements.
